(...) Thx, Marco. I'm investigating! btw, Do you mean that they communicate through a standard lead attached to sensor inputs, say, or some other electrical connection? Interesting that the CM can't communicate at speed, but the MS & CP will. I'd (...) (24 years ago, 20-Mar-01, to lugnet.technic, lugnet.robotics)

(...) You can buy both turntables and chains from the Pitsco Dacta people (neither are very cheap!) 35 chain links really don't go very far - each link ends up being only the size of two gear teeth. It takes 20 links just to go once around a 40t (...) (24 years ago, 20-Mar-01, to lugnet.robotics)

| | Solar-Powered Hexapod Walker
|
|
I built a simple solar-powered hexapod last weekend with some new parts I ordered from Pitsco. The walker is quite slow, using the LEGO solar cell to power a 5225 9V motor, which drives a worm gear coupled directly to a 24T gear. I've found the LEGO (...)

Another way to gather chain links is to pick up the semi-older motorbike sets from ebay, which generally go for sensible prices. I'm referring specifically to sets 8838 and 8422. Clocking at 240+ and 310+ pieces, they provide plenty of non-beam (...) (24 years ago, 20-Mar-01, to lugnet.robotics)

| | Small pneumatic cylinder
|

Hello, Does anyone know where I can buy the small pneumatic cylinder, #5116? I am trying to build an all pneumatic 2-legged walker, and need one to turn the leg. I could use a motor, but I do not want all the extra weight of 2 motors, and I would (...) (24 years ago, 20-Mar-01, to lugnet.robotics)

Regarding the solar powered walker and the mars rover, both are cool looking robots! I find that solar panel particularly interesting. Perhaps put a solar panel on each side, with each panel connected to one side of the robot... So when there is (...) (24 years ago, 20-Mar-01, to lugnet.robotics, lugnet.technic, lugnet.dacta)
